Answer:
Determinant are special number that can only be defined for square matrices.
Step-by-step explanation:
Determinant are particularly important for analysis. The inverse of a matrix exist, if the determinant is not equal to zero.
How to find determinant
For a 2×2 matrix
For a 3×3 matrix
we first decompose it to 2×2
Example
Find the values of λ for which the determinant is zero
Equating the determinant to zero
s = * (1 ±5 )
s = 1.61 or -0.61
>= means the greater than or equal symbol
n-73>=438
n>=511
Answer:
v = 24
Step-by-step explanation:
Ft + mu = mv
v = (Ft + mu)/m = (55*3 + 5*(-9))/5 = 24
